log: do not shorten decoration names too early

Browse Source 
The DECORATE_SHORT_REFS option given to load_ref_decorations()
affects the way a copy of the refname is stored for each decorated
commit, and this forces later steps like current_pointed_by_HEAD()
to adjust their behaviour based on this initial settings.

Instead, we can always store the full refname and then shorten them
when producing the output.
